Abstract

The invention discloses a simulation method, device and equipment for combined heat and power random production of an integrated energy system. Considering that other energy sources such as renewable energy will also have an impact on the integrated energy system in addition to electric power units, the power sequence load data Separate the net electricity sequential load data, and then construct the initial combined heat and power probability density function according to the net electric sequential load data and thermal load data to ensure the accuracy of the initial combined heat and power probability density function, and simulate the units in the integrated energy system Putting into operation, according to the performance index of the unit, the initial combined heat and power probability density function is corrected and calculated to obtain the equivalent combined heat and power probability density function, and finally the reliability index and economic index of the integrated energy system are calculated based on the equivalent combined heat and power probability density function , which is more in line with the characteristics of the coordinated coexistence of multiple energy sources in the integrated energy system, and realizes the accurate evaluation of the reliability and economic value of the integrated energy system.

Description

technical field [0001] The invention relates to the technical field of energy dispatching, in particular to a simulation method, device and equipment for combined heat and electricity random production of an integrated energy system. Background technique [0002] The integrated energy system (Integrated Energy System, IES) takes the power system as the core, organically coordinates and optimizes various energy sources, optimizes the distribution, conversion, storage, and consumption of various energy sources such as electric energy, natural gas, and cold / heat, and supplies loads An energy system that requires cooling and heating power and makes full use of renewable energy. Economic analysis and reliability evaluation during operation are indispensable parts to promote the development of integrated energy systems. [0003] Probabilistic Production Simulation (PPS) is under the future load curve, considering the random outage of the unit and the random fluctuation of the loa...
